TRAC'IION-MACHINE HITCH FOB SEEDERS.

Application ied January 8, 1920. Serial No. 350,103.

y inve-ntioii is to provide a means for attaching or connecting a group of seeders to the rear portion of a traction machine of the type thatr is guided by 5 a walking operator.

A further object is of this type of s seeding devices to provide a machine uch construction that the can perform their functions equally well on smooth or uneven ground.

A further, and particular object is to provide such ahitch or connection between the frame of the seeder and the traction machine that oscillation of the traction machine is permitted without changing the seeder.

the position of Other objects of the invention will ap ear from the followingl detailed description.

The invention consists generally in various constructions and inafter described out in the claims.

In the accompanying combinations, all as hereand particularly pointed drawings forming part of this specification,

Figure 1 is a p lan view, partially in section showing the relative arrangement of the traction machine and seeder and the hitch or connection between them,

Figure is a longitudinal sectional view,

2-2 of- Figure 1,

Figure 3 is a sectional view., on the line 8-3 of Figure 2,

Figure 4 is a sectional view on lla of Figure 2.

In the drawing,

the traction mach porting wheels 3 and the line 2'represents the frame of ine, having the usual supon the frame 2 and supporting the steering or handle bars 5 by chine is guided. the bracket i and a casting 8 in which the steering mounted and slidable..

means of vwhich the ma- Aii arm G is mounted on a rod 7 is connected with posts are The arm 6 is provided with a compression spring 9 which normally holds the steering posts in their raised position. provided locking A latch mechanism 10 is the posts when raised.

This above described part of the machine is only incidental to this case.

The bracket t i s provided with a stud 11 preferably cast therein and project-ing` rearwardly under the 12 is mounted to seated atone end steering posts and a yoke rock on said stud and is against the bracket 4 and 4 is a bracket mounted y ends are provided with clampsV 19 secured by set screws 20 and rods 21 have vertical pivots on said clamps and are provided with caster wheels 22. Between these caster wheels the implement frame of the seeder proper is arranged and I will now describe it in detail.. y l

I prefer to make this implement frame of angle bar metal Qn account of its strength and rigidity in proportion to its weight, and the forward portion consists of a head bar 23 and the rear portion, of a rail 39, with intermediate cooperating parts hereinafter described in detail.V A draft rod 24 is connected at its rear end to the bar 2 3 and is provided with braces 25.y The forward end of the draft rod extends beneath the traction machine to a position substantially concentric with the vertical axis of the machine or at a. point directly beneath the axle of the supporting wheels.A A socket 26 is provided in the forward end of this draft rod 24 to receive the downwardly turned end 27 of Va rod 28, the rear end o f which is inserted into a socket 29 in a castingI 30 that is mounted on the draft bar 17 and secured thereon by suitable, means, such as a clamping bolt 31. A set screw 32 secures the end yof the rod 28 in` its socket so that forward movement of the traction machine transmits power through the rod 28 to t-he draft rod 2li and to the frame of the seeder to which the draft rod is attached.

I have shown a row of three seeders mountedin the frame but do not, of course, confine myself to this number, as a greater or less numberv may be used, as preferred. The seeder is a type which I prefer to purchase in the open market and as its inechanism is well known, and in general use, I will merely refer to the diiferent parts without attempting to describe its construction or operation in detail. F or convenience of description, I will designate the seeder in the center as A. and those on each side as B, Each of these seeders has furrow discs or wheels 33 and the rear hollow-faced wheels 34 and seed containers 35. The middle seeder has rails 36 and 37 pivoted at 33 to the head rail 23 and the rail 39 parallel wit-h the rail 23 and in the rear thereof is rigidly connected with the bars 36 and 3.7 by suitable braces 40. This construction provides for a rigid support of the middle 'seeder on the frame. Each seeder has, of course, the usual boot or shoe 4l through which the seed is deposited in the furrows under the machine. The seeders B are provided with similar bars 36 and 37 which I will designate by the same reference numeral by the addition of the exponents a and b, and they are arranged in substantially the same relation with respect to the frame of the seeder except that the bars 36a and 37:l and 36 and 37b are rigidly secured at their forward ends to the head bar 23. The frames of the seed-- ers proper are all pivoted in a corresponding manner at 42 and are free to oscillate on their pivots and to prevent the wheels 34 from dragging on the ground when the seeder frames are raised, as will be hereinafter described, l prefer to provide the bars 37, 37a, and 37b with inwardly turned end portions 43 in position to engage arms 44 mounted on the frames of the seeders for the purpose of raising the krear portion of the seeders and the wheels out of contact with the soil, as when the machine is being turned or at any other time when the operator does not desire the seeder wheels to contact with the ground. The frame of the seeder A has straps 45 rigidly connecting it with the bar 39 and to these straps the braces 40 are attached, as shown in Figure 3. Rods 46 have forked ends pivotall.v7 connected at 47 with the bars 35 and 3T@ and 361 and 37b and the uppery ends of these rods are slidable in sockets in the bar 39. Collars 48 and 49 are mounted on these rods 46 above and below the bar 39 and suitable Compression springs 50 are mounted on ythese rods between the collars 49 and 'the bar to yieldingly resist upward movement of the seeder frames with which they are connected but allowing them to rise and fall with the inequalities of the ground over which the machine may be moving. rlhe adjustment of the collars 48 enables the operator to set the seeder frames at any desired elevation. Figure 3 plainly illustrates this construction, the middle seeder being rigid while those on each side are free to slide vertically in the rear rail of the seeder frame and accommodate themselvesto the surface of the ground.

The steering bar 5 extends backwardly over the seeder frame and lifting straps 5l are provided connecting the posts with ears 52 on the bar 39. These lifting straps have adjustable collars 53 to allow the distance between the rods and the seeder frame to be varied, as desired.
